The Trump administration has reversed a ban on using neonicotinoid pesticides (linked to declining bee populations) and genetically modified crops in over 50 national wildlife refuges (out of 560 total).

It has also been reported recently that the Trump administration is opposing the World Health Organisation’s guidelines on limiting antibiotic use in healthy farm animals (read more here).
